Aside from Pokemon figures, there's a few posters I have, but I'm too lazy to take pictures right now. As for strategy guides, I have the Pokemon Platinum, Pokemon HeartGold & SoulSilver (Volume 2), Pokemon Black & White (Volume 1), and PMD: Red/Blue Rescue Team official guides.
EDIT: And for games, hmm...
Pokemon White
Pokemon SoulSilver
Pokemon Platinum
PMD: Explorers of Sky
Pokemon Battle Revolution
Pokemon Rumble (If WiiWare games count)
PMD: Blue Rescue Team
